cient, it is a most convenient mode for travel- 

 lers, who may not have the opportunity of im- 

 mersing them in boiling water. With respect 

 to the smaller species, they arc, in general, soon 

 killed, as passing the pin through them will fre- 

 quently deprive them of life in a few minutes ; 

 but the usual method is, to collect the very mi- 

 nute moths in separate pillboxes, and kill them 

 by the fumes of sulphur. The following is the 

 best method of effecting this : elevate the lid of 

 the box sufficiently to admit the fumes of the 

 sulphur, without letting the insect escape ; then 

 place the box under a bason and light a match, 

 or put a little sulphur on the end of some paper, 

 and place it under the bason : in the space of a 

 few minutes the insects will be all killed, and 

 may then be pierced and put away into boxes.
